9 Facts About Redheads You Never Knew

Having pale skin may mean that redheads burn more easily when exposed to UV rays, but their paleness can serve as an advantage. Redheads can't absorb sufficient Vitamin D due to low concentrations of eumelanin in their body. Headstrong as it is, ginger hair holds its pigment much firmer than any other hair colour. If redheads desired to dye their hair to any other colour (why would you?), it would only have a noticeable difference after bleaching the hair beforehand. Otherwise, the colour won't take. Bleaching, of course, is just bad news for hair. Especially red hair, which is much more fragile than other shades anyway.
